Nano silver sterilization coating

Experts from the Russian Institute of Electrochemistry have developed coatings containing nano-sized silver particles. This kind of paint can effectively kill many kinds of bacteria attached to the surface of the board when it is coated on the board, and its bactericidal effective performance is maintained for nearly 8 months.
According to the latest issue of the Russian Journal of Chemistry and Life, there are two methods for producing such nanosilver. One is to ionize radiation with a silver solution similar to heptane, and the other is to prepare a variety of flavonoids first. Plant pigments, and then let these pigments chemically react with the silver solution. Using the above two methods, a slightly tan colored transparent colloidal liquid can be obtained. The liquid contains a certain amount of silver particles, and the size thereof is about tens of nanometers. In comparison, the second method is simpler, more economical and effective.
According to Kudriavtsev, an expert in charge of the above research, silver particles with a size of only tens of nanometers are more biochemically active than ordinary silver particles, and the transparent colloidal liquid containing such silver particles Strong bactericidal ability. Adding a small amount of this liquid to paints, pigments, enamel paints, etc. can achieve bactericidal properties. In the experiment, the researchers placed the clay plates, wood plates, and steel plates coated with the nanosilver bactericidal paint on culture fluids containing pathogenic bacteria such as Escherichia coli, Legionella pneumophila, Salmonella, and Staphylococcus, resulting in adherence. All kinds of bacteria on the surface of all plates died in less than 4 hours.
